Aluminum Alloy, Sheet and Plate, Alclad 4.4Cu - 1.5Mg - 0.60Mn (Alclad 2024-O, Sheet and Plate) Annealed; or when specified, “As Fabricated” (2024-F) (Composition similar to UNS A82024)
AMS4461
1.1 Form
This specification covers an aluminum alloy in the form of sheet and plate 0.008 to 1.750 inch (0.203 to 44.450 mm) thick, supplied in the annealed (O) condition (see 8.4). When specified, product shall be supplied in the “as fabricated” (F) temper.
1.2 Application
These products have been used typically for formed structural parts which will be subsequently heat treated, but usage is not limited to such applications.
1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment; ARP823 recommends practices to minimize such conditions.
Rationale: AMS4461C results from a Five-Year Review and update of this specification. This standard is being reviewed as part of the SAE Five-Year Review policy. The committee will look at possible changes to ordering information and other potential updates throughout the standard.
